5/11 = 18/y
5 y = 18 · 11
5 y = 198
y = 198 : 5
y = 39.6
The approximate side length of a square game board with an
area of 184 in^2 is 14 inches
<h3>Area of a square</h3>
The formula for calculating the area of a square is expressed as;
A = l^2
where
l is the side length of a square
Given the following parameters
A = 184 square inches
Substitute
184 l^2
l = √184
l = 13.56
Hence the approximate side length of a square game board with an
area of 184 in^2 is 14 inches

The point-slope form:

We have slope=m=8, and the point (-5, -3). Substitute:

18.
The formula of a slope:

We have the points (3, 4) and (15, 10). Substitute:

The point-slope form:

or

Answer:

Step-by-step explanation:
Given

Required
Rewrite using scientific notation, then find n

Express as fraction

This can be splitted to

The first number must be between 1 and 10; hence, 25 can be expressed as 2..5 * 10

Apply law of indices


Comparing n, the given options

Using the z-distribution, the 95% confidence interval of the population mean is: (17.5, 24.5).
<h3>What is a z-distribution confidence interval?</h3>
The confidence interval is:

In which:
is the sample mean.
is the standard deviation for the population.
In this problem, we have a 95% confidence level, hence
, z is the value of Z that has a p-value of
, so the critical value is z = 1.96.
For this problem, the other parameters are:

Hence the bounds of the interval are:


The interval is: (17.5, 24.5).
